I’m doing it currently and some of the posts on this thread are seriously ill informed. Fair enough if the diet isn’t for you but it’s not as restrictive as people are suggesting.
i started on 22 November and have lost 20lbs since then relatively easily and still enjoying my food. If you are a reasonable cook, it’s fine. It doesn’t work if you rely a lot on pre-prepared or processed foods.
As others have said there are 4 phases
Phase 1 which is only 2 days is effectively a 2 day fast. You can eat unlimited vegetables but no oil, dairy or gluten.
Phase 2 lasts 14 days and is also strict. It’s effectively a low carb, low fat phase. You eat meat, dairy, veg in controlled portions but no added fats. The amount you can eat depends on how much you weigh - 120g of each is the absolute minimum and only for those who are petite and not very heavy!
Phase 3 (which is where I am) is absolutely fine. In Phase 3, you add in olive oil, bread, alcohol and chocolate and also have one mandatory treat meal per week where literally anything goes which makes it easy to maintain a social
life or fit around work commitments.
A typical days food for me at the moment for example might be:
breakfast - 2 scrambled eggs with sautéed mushrooms and a slice of rye toast
Lunch - smoked mackerel fillet with a mixed salad, vinaigrette dressing and an apple
Dinner - duck breast with celeriac purée and green beans. Glass of wine. Few squares of dark chocolate.
I don’t eat between meals any longer and have given up on soft drinks including diet drinks and I tend to have my tea or coffee after a meal as recommended rather than between meals but I’m not completely hard and fast on that.
Once a week, I either eat out, have a takeaway, or eat with friends and I choose freely what I would like with no restrictions as to amount or what I’m eating. So last night it was a friends birthday and we had champagne, wine, a restaurant meal in a Lebanese restaurant, cake and coffee.
I am 55 and was finding it hard to kickstart weight loss but the structure of this diet has worked for me. It won’t for everyone but I don’t agree with the comments that it is unduly restrictive (other than for the first 16 days - phases 1 and 2 - which I see as more of a mental reset and reframing than a physical one). The hard fact is that for those of us who have weight to lose, the reason for that is because we have been eating too large a volume of food and/or not the correct balance of foods. To lose weight it’s inevitable that we will need to both eat less and eat differently. The HBD is just one way of doing that!
